Abstract

The invention provides a medical antibacterial acupuncture-resistant rubber plug and a preparation method thereof. The rubber plug is prepared from brominated butyl rubber, hard acid ester, zinc oxide, sulphur, titanium dioxide, calcined kaolin, accelerant ZDC, accelerant DM, 2-mercapto benzimidazole, ethylene-ethyl acrylate copolymer, styrene-isoprene-styrene triblock copolymer, rhizoma alpiniae officinarum extracts and rhizoma acori tatarinowii extracts. The rubber plug is prepared through mixing, rolling forming, vulcanizing, trimming, cleaning, sterilizing and drying. The medical antibacterial acupuncture-resistant rubber plug has a low puncture exfoliation rate and a good puncture capacity, and meanwhile the rubber plug has good antibacterial activity.

Description

technical field [0001] The invention relates to the field of medical rubber materials, in particular to a medical antibacterial and needle-resistant rubber stopper and a preparation method thereof. Background technique [0002] Medical rubber stoppers require rubber materials that are non-toxic, odorless, tasteless, and extract-free, resistant to pharmaceutical chemicals, and can withstand repeated heating and disinfection, good self-sealing, acupuncture resistance, low air permeability, and water permeability. Due to the advantages of good air tightness, heat resistance, acid and alkali resistance, and chemical inertness, butyl rubber stoppers soon replaced natural rubber stoppers in the field of pharmaceutical packaging. At present, more than 90% of rubber stoppers for pharmaceutical packaging are produced with butyl rubber as the base material. However, there are still some problems in the application of butyl rubber stoppers. The most prominent problem is the problem of...
